Energy Efficiency: Saving on energy costs is another advantage to installing fiberglass doors. A fiberglass door is filled with polyurethane foam, which offers five times more energy efficiency than wooden doors can provide. The framed glass entrance doors have either a double, or triple pane, to help cut on cooling and heating costs.

To a business which is considering steel security doors there are many choices open, and the buyer will know that they are getting a door that meets their unique needs after discussing the many options with a professional supplier.

Other than the inner foam, these doors have other insulating enhancements in the form of high efficiency sealing systems to further keep out sound and the elements.
